The tour will be made up of 25 individual photo spheres, which essentially means 25 places in the spring where online users can navigate to and pan 360 degrees. For each sphere, Ulloa identifies a “node” (central point for a sphere) and takes between 10 and 30 photos while pivoting in a circle, being careful to keep the camera over the central node. Next, he takes one photo with the camera pointing directly up toward the sky and one looking directly down at the ground. The wide-angle fisheye lens and multiple photographs allow him to cover the 360 degree view.
